T13 what are you talking about lol. MPACK is the folder that has all the DYOM files. (DYOM mod how ever you want to call it). MPACK is the folder that you can select from the start of the game (when selecting "Start New Game") DSL is the folder where you need to install Storylines.

MPACK's were an unused feature, and Dutchy and Patrick made use of them.MPACK's contain the DYOM files, and you need to place these in the GTA SA User Files folder.

Not only Dutchy and PatrickW use this feature, I think every scm coder use this for testing there missions and this function is also used by Rockstar to test Raw Missions while Game Making, I read this on a website.... .
